The cartoonist - who writes the series as part of his exclusive contract with DC - has promised an "epic" four-issue storyline beginning in issue #8.
"It's the longest storyline that I've done so far," he told Newsarama. "It's going to be a four-parter called 'The Rise of the Hollow Men'. It's the culmination of all those little plot threads and seeds I've been planting over the first seven issues.
"They all come to a head in this big, epic story that I've been planning since I got on the book. It's been a lot of fun getting to write what I've been planning and teasing for the last year. It goes through to Issue #11. It even touches on the time of the Viking Prince. So it's a big spanning epic."
He also said that this week's issue #7 would see the return of Superboy's dark, Lex Luthor-influenced side.
Superboy was recently nominated for the 2011 Eisner Award for 'Best New Series'.
Lemire is currently also working on the Flashpoint: Frankenstein and the Creatures of the Unknown miniseries tying-in to DC's upcoming event and said that he had more projects coming up following the conclusion of 'Flashpoint'.
